# The parameters related to radiometric calibration in Hayabusa2 ONC
# L2c and L2d creation are listed in the below.
# These values are defined for each camera.
# In the case of ONC-T, they are defined for each band.
#
# (1) Effective band center for each camera [um].
# 
# (2) Effective bandwidth for each camera [um].
# 
# (3) Effective solar irradiance in [W/m^2/um)]
# 
# (4) Effective sensitivity in [count/sec/(W/sr/m^2/um)]
#
#     The sensitivity is defined by the following equation: 
# 
#        S = S0(period) * { 1 + S1(period) * ( t - t_start(period) ) }
#            * ( a_CCD * (T_CCD + 30 degrees Celsius) + 1 )
# 
#     where
#              t: time in days,
#          T_CCD: CCD temperature in degrees Celsius,
#       period 1: before TD1,
#       period 2: between TD1 and TD2,
#       period 3: after TD2.

# Effective band center for each camera bc [um].
# Effective bandwidth for each camera bw [um].
# Effective solar irradiance in  [W/m^2/um)]
# a_CCD. No data for ONC-T wide, w1 and w2. ONC-T V band value is used for the moment as the representative values.
# Parameters for sensitivity for period 1: t_start_in_YYYY-MM-DDThh:mm:ssZ(1),S0(1),S1(1)
# Parameters for sensitivity for period 2: t_start_in_YYYY-MM-DDThh:mm:ssZ(2),S0(2),S1(2)
# Parameters for sensitivity for period 3: t_start_in_YYYY-MM-DDThh:mm:ssZ(3),S0(3),S1(3)
